Determination of ED and ED of Oliceridine combined with Propofol in inhibiting responses to gastroscope insertion: a biased coin up-and-down design.

Background: Gastroscopy is a common medical procedure, but the insertion of the endoscope often causes significant discomfort and anxiety in patients, necessitating effective sedation strategies. Traditional sedatives, such as propofol, are widely used for procedural sedation but can lead to adverse effects, including respiratory depression and cardiovascular instability at higher doses. Oliceridine, a novel opioid analgesic, has emerged as a potential alternative due to its biased agonist properties, which may provide effective analgesia with a more favorable side effect profile.

Predictive value of left atrial strain for left ventricular reverse remodeling in dilated cardiomyopathy.

Background: Early prediction of left ventricular reverse remodeling (LVRR) can guide the subsequent treatment in dilated cardiomyopathy (DCM) patients. We aimed to investigate the value of left atrium (LA) strain for predicting LVRR in DCM patients.

Methods: Clinical and imaging data of DCM patients were gather between January 2018 and January 2023.

MRI features of an atypical case of extraventricular neurocytoma: A case report.

Rationale: Central neurocytoma occurring outside the ventricles is known as extraventricular neurocytoma (EVN). EVN is rare and its magnetic resonance imaging (MRI) findings vary greatly and overlap with the imaging features of other intracerebral primary tumors.

Patient Concerns: A 21-year-old woman with an intrauterine pregnancy of 18+2 weeks complained of dizziness and headache for 3 months.

Left ventricular myocardial strain in ventricular arrhythmia without structural heart disease using cardiac magnetic resonance.

Ventricular arrhythmia (VA) in structurally normal heart is considered as benign. However, these arrhythmias have been recently reported to induce left ventricular (LV) dysfunction. Up to now, there is no efficacious method to detect abnormal myocardial systolic function in VA patients.

Evaluation of left ventricular strain in patients with dilated cardiomyopathy.

Objective Dilated cardiomyopathy (DCM) can cause structural and functional changes in the left ventricle (LV). In this study, we evaluated whether cardiac magnetic resonance tissue-tracking (MR-TT) can be applied to the detection of LV abnormalities in patients with DCM. Methods We used MR-TT to analyze the global peak radial strain (GPRS), global peak circumferential strain (GPCS), and global peak longitudinal strain (GPLS) in every segment of the LV in 23 patients with DCM and 25 controls.
